Application July 2, 1953, Serial No. 365,693

1 Claim. (Cl. 215-79) The present invention relates to a liquid pourer and more particularly relates to liquid pourers intended to be placed over the mouth of a bottle to take the place of the conventional bottle closure whereby the contents of the bottle may be poured out when the bottle is tilted.

The primary object of the invention is to provide a liquid pourer for bottles, which pourer includes a cap which may be threaded over the neck of the bottle or inserted into the neck of the bottle, which cap is provided with a removable pourer insert which includes a pouring spout projecting exteriorly of the bottle and a vent tube projecting into the interior of the bottle.

Yet another object of the invention is to provide a liquid pourer whereby a plurality of sizes of pouring spouts may be selectively mounted in the pourer cap without the necessity for providing separate caps.

A still further object of the invention resides in the provision of a liquid pourer which may be easily and quickly assembled and disassembled for cleaning, which is inexpensive of manufacture, durable in use and compact in its assembly.

These, together with various ancillary objects and features which will later become apparent as the following description proceeds are attained by this invention, a preferred embodiment of which is shown by Way of example only in the accompanying drawings, wherein:

Figure 1 is a front elevational view of the upper portion of a bottle neck with the pouring cap of the present invention attached thereto;

Figure 2 is a cross sectional view of the pouring cap and bottle neck of Figure 1, taken substantially along section line 2-2 of Figure 1;

Figure 3 is a cross sectional view of the pourer cap taken substantially along section line 33 of Figure 2; and

Figure 4 is a cross sectional view in side elevation of a modified form of the invention.

Referring now to the accompanying drawings in detail wherein like reference numerals are utilized to designate similar parts throughout the various views, attention is first drawn to the form of the invention disclosed in Figures 1-3.

In this embodiment of the invention, the pourer cap is designated in its entirety by the numeral 10. As shown, the pourer cap is mounted on the upper portion of the neck 12 of a bottle.

The pourer cap 10 comprises essentially a disc shaped closure cap 14 and a pourer insert 16.

The disc 14 is provided with a depending peripheral skirt 18 which is threaded on over the mouth of the bottle neck 12 by means of the cooperating threaded portions 20 and 22 on the external surface of the bottle neck and the inner wall surface of the skirt 18. The closure cap 14 is also provided with a central or axial threaded bore therethrough.

The liquid pouring insert 16 consists primarily of a cylindrical plug 26 which is threaded into the bore 24. Formed integrally on the plug 26 is an upwardly projecting hollow pouring spout 28 which is curved forwardly 2,727,644 Patented Dec. 20, 1955 at its upper end to facilitate pouring. A hinged flap 30 closes the outer end of the pouring spout 28 in such a manner that upon tilting of the bottle, the flap will open to allow liquid to flow through the spout.

Projecting inwardly from and to one side of the pourer spout 28 on the plug 26 is a vent tube 32. This tube extends into the interior of the bottle to vent the same as the liquid is poured through the spout 28. As will be noted from Figure 2, the vent tube 32 opens into the upper surface of the plug 26 to communicate the interior of the bottle with the atmosphere whereas the pourer spout 28 opens into the lower surface of the plug 26 to communicate the spout with the interior of the bottle. The bore communicating the spout 28 with the interior of the bottle 12 is designated by the numeral 34 whereas the bore communicating the vent tube 32 with the atmosphere is designated by the numeral 36. Although in the drawings the spout 28 and the vent tube 32 are shown as being integral with the plug 26, quite obviously they may be separate members welded or otherwise attached thereto.

Thus, the pouring cap 10 is such that once the closure cap 14 is mounted upon the bottle, it need not be removed for any purpose; however, if it is desired to clean or polish the spout 28 and clean the vent tube 32, it is only necessary to twist the insert 16 in its entirely out of the bore 24 and the closure cap 14. Also, in this same vein, if a difierently configurated pouring spout 28 or a larger vent tube 32 is necessary to assure the proper dispensing of the liquid from the bottle 12, a variety of types and shapes of spouts and vent tubes may be provided on identically shaped plugs 26 whereby only the insert 16 need be replaced and the closure cap 14 can remain firmly sealed on the bottle.

In the modified form of the invention shown in Figure 4, the pouring cap is illustrated in its entirety by the numeral 38 and consists of a stopper 40 frictionally seated in the mouth of a bottle neck 42 and having a central bore 44 therethrough. An annular recess or groove 46 is formed in the Wall of the bore 44 adjacent the upper end thereof and a metal bushing 48 is inserted into the bore 44 and is provided with an annular flange midway between the ends thereof which seats in the groove 46 to provide a seal for the bushing and to retain the bushing in place in the bore. The bushing is internally threaded as at 52 and a pouring insert 5'4 in the form of a cylindrical plug 56 is threaded into the bushing.

The plug'56 is provided with a pair of bores 58 and 60 therethrough. A pouring spout is formed integrally with and projects upwardly from the upper surface of the plug 56 and is designated by the numeral 62. This pouring spout 62 opens into the bore 58 to communicate the pouring spout with the interior of the bottle 42. Projecting from the lower surface of the plug 56 is a hollow vent tube 64 which opens into the bore 6G to communicate the interior of the bottle with the atmosphere. Thus, in this form of the invention also, the pouring spout and vent tube insert 54 may be removed for cleaning or replacement with ditferent sized spouts and tubes without disturbing the sealing connection of the stopper with the mouth of the bottle.

In both forms of the invention therefore, and particularly in the second form of the invention, when the closure portion or bottle cap portion of the pouring cap becomes deteriorated through use or is not of the size to fit the particular mouthed bottle, it is not necessary to provide a completely new pouring spout arrangement, but it is only necessary to remove the pouring spout from another sized closure cap, such as 14 or 40, and replace it in a cap that will fit the particular bottle.

From the foregoing description the construction and utility of the invention are believed to be readily apparent. However, since numerous modifications will readily occur to those skilled in the art, after a careful consideration of the foregoing specification taken in conjunction with the accompanying drawings, it is not desired to omit the invention to the exact construction shown and described. But, all suitable modifications may be resorted to which fall within the scope of the appended claim.

What is claimed as new is as follows:

A pouring device for a bottle comprising a closure adapted to close the mouth of a bottle and having an axial opening therethrough, a pouring insert including a spout having a lower end provided with an enlarged eccentric plug integral therewith, a vent tube integral with said plug and depending therefrom at one side of the spout, and an internally threaded bushing in said opening having a flange embedded in the closure, said being removably threaded into said bushing.
